The ECU controls them. The connections are already on the non 3 stage manifold clipped out of the way and unhooked. Once you install the manifold you use the connectors on the DISA motors.

I wonder how they differ.
An educated guess would be where the oil separator connects to the back of the intake. Some have a single inlet into the manifold and others have two inlets. Either way, you can get the corresponding hose that connects it up.

It could be something else, but I am not seeing anything else in my head it could be.

Yes, you can get the manifold installed even with the tune already on. You will want to have the AA stage 2 tune however.

Most people not getting a tune see ~9whp gains and then coupled with the tune they see between 25-35whp gains.
